I think you misunderstand my intent. It is not to say that there is anything wrong, per-se, with playing a game in a manner that is wholly contrary to its themes. However, that is, by definition, perverse.
"Ludonarrative dissonance is the conflict between a video game's narrative told through the story and the narrative told through the gameplay."
examples:
- Cyberpunk 2077 - Your character is dying of a virus and needs to quickly find a cure. Meanwhile youre doing a whole bunch of side quests that take a lot of in game time.
- Any RPG - Characters can be endlessly revived using items but die permanently in cut scenes.
- GTA4 - Main character is trying to leave their violent past behind them. Meanwhile you can blow people up with an rpg.
I don't think that's by definition wrong for stardew valley. That's your interpretation based on the intro. The developer might not find it perverse to play that way at all.
